The following are reasons why the allies won World War I.
- Allied powers had many supporters drawn from 25 states some of which were Britain, France, Belgium, Russia, Italy, USA, Japan and Portugal. They had more manpower than the central powers.
- Germany failure to effectively control her expensive colonies and others turned against her.
- USA entry into war on the side of the allies accelerated the defeat of the central powers. The industrial might of USA and her economic wealth helped the Allies to force the central powers to their knees.
- The Allies had able and focussed political leaders like Lloyd George-the British Premier and Georges Clemenceau, the French Premier.
- Germans/axis powers made serious technical mistakes like invasion of the neutral Belgium by Germany which turned the world opinion against the central powers.
- Superior naval power of the Allies. The superiority of the British Royal Navy enabled the Allies to enforce a naval Blockade that caused severe food shortages among the central powers.
- Germany fought the war on many fronts.
- Germany was badly led down by her colleagues like Italy who decamped and Bulgaria and Austria-Hungary who had to be assisted all the time. Turkey on her part easily accepted defeat.
- The Allies had financial and industrial resources in Europe and in their colonies which were used to great advantage during the war.
- The Allies had powerful weapons e.g. they used Tankers, Aircraft and Battleships.
- The allies were united under the Command of General Foch which disadvantaged the central powers. German also used young and inexperienced soldiers after 1918 due to heavy causalities.
- The central powers were surrounded by the Allies as they lay in the centre of Europe. They also lacked an extensive coastline and thus were easily blockaded.
